Specification of Letters Patent.

Application filed October 19, 1910. Serial No. 587,817.

To all whom it may concern:

Be it known that I, EMIL JAGENBERG, a citizen of Germany, residing atDusseldorf, Germany, have invented a new and Improved Label Gumming andAttaching Machine, of which the fication.

This invention relates to a machine of novel construction for gumminglabels and.

securing the gummed labels to suitable objects.

The machine is simple in construction, operates quickly, is accurate andthoroughly reliable in its movements.

In the accompanying drawing: Figure 1 a side elevation of a machineembodying my invention; Fig. 2 a section through the drum. tongue andcooperating parts, and Fig. 3 a similar section showing the parts in adifferent position.

Upon a rotating shaft c is mounted a drum (1 composed of a pair ofspaced disks connected at their periphery by one or more segments 6. Thelabels are stacked in a magazine a pivoted to a slide c, which is guidedon the machine frame tangentially to drum a, so that as the slide movesobliquely upward, the bottom label will impinge against segment 7). Uponshaft 0 is mounted a cam 7", which engages a cam roller journalcd in anarm 0' of slide 0. The contour of the cam is such that after the bottomlabel has engaged segment 6, the speed of the further ascending slide isequal to the speed of the segment. In this way the bottom label willadhere to the segment snugly and without wrinkles, the segment havingbeen previously coated with an adhesive by rollers 9. Upon the furtherrotation of drum (1, the bottom label will be drawn out of the magazine,while the superposed labels will be held against withdrawal by hooksformed at the mouth of the magazine, and against which they are pressedby a follower h.

Upon the machine frame is guided a horizontally movable tongue 2'provided with a number of spaced relatively fixed jaws 71: adapted toengage transverse grooves 71 of segment I), and spaced movable jaws Z.At its rear end tongue 2' is connected to rod m pivoted to elbow lever nwhich engages a cam 0 fast on a countershaft p driven from shaft Movablejaws l are provided with an arm I] having a roller whichis spring heldagainst the bottom of a horizontally following is a speciarrangedvertically movable rail 9*. This rail is connected at one end to apivoted arm 8 and at its other end to a pivoted elbow lever 25 whichoperatively engages the cam u.

Tongue i is advanced by cam 0 when segment 7) occupies approximately itsuppermost position, so that the lower jaws 7: will enter grooves 72 tobe located below the forward end of the label adhering to said segment.Simultaneously therewith cam u will so swing lever t, that rail 7' israised, to lower jaws Z upon the label and thereby clamp it to jaws 7c.Jaws is, Z are then retracted by cam 0 with a speed equal. to that ofsegment 7) so that the label is peeled oil the same. The jaws finallyattach the label to the object v which has been brought into theposition illustrated in Fig. 1 immediately after segment I) has clearedport 1 during its continued rotation. Cam 0 is so shaped that the jaws70, Z come to a temporary standstill during the above label grasping andattaching operations, so as to insure a reliable working of the machine.

The attachment is effected by a plunger, or by elevating the objectagainst a suitable supabutment. During the receding motion of thetongue, movable jaws Z are opened to liberate the label. Of course thetongues may be so placed as to cooperate with the segment when thelatter arrives at its bottom or other position.

I claim:

1. In a label gumming and attaching machine. a continuously rotatingsegment, means for applying an adhesive'thereto, means for applying alabel to said segment, a clamping jaw movable in substantialtangentiality to said segment, means for advancing and collapsing thejaws to grasp the label, and means for retracting the jaws with a speedequal to that of the segment to peel the label ofl" said segment andattach it to an article, the jaws being at a temporary standstill duringsaid label grasping and attaching operations.

2. In a label gumming and attaching machine, a continuously rotatingsegment having a grooved edge, means for applying an adhesive thereto,means for applying a label to said segment to partly overlap itsgrooves, clamping jaws movable in substantial tangentiality to saidsegment and adapted to enter said grooves, means for advancing andcollapsing the jaws to grasp the overlapping label section, and meansfor retracting the jaws with a speed equal to that of the segment topeel the label off said segment and attach it to an article, the jawsbeing at a temporary standstill during said label grasping and attachingoperations.
